SIG's MCX Spear-LT is the lightweight member of the Spear family, built around a short-stroke gas piston rather than direct impingement. The practical advantages are a cleaner, cooler bolt carrier and much better behavior when a suppressor is attached, which is why the platform has been so popular with agencies and suppressor users. It also folds at the stock, which no standard AR can do, making it far easier to store or transport. This one wears a 16-inch barrel in 5.56 NATO with an FDE finish and a free-floating M-LOK handguard.

It is a genuinely modern rifle, not a warmed-over AR.
